1. 1. 2D Reflection Seismic Imaging of Rødby Structures, Denmark: Geological Conditions for CO2 Sequestration

   Master-uppsats, Uppsala universitet/Geofysik

   Författare :Mussie Habtemariam Zeru; [2024]
   Nyckelord :Reflection seismic; Geologic carbon storage; Sandstone; Structures; Rødby;

   Sammanfattning : Amidst the global climate action movement, geologic carbon storage (GCS) has emerged as a pivotal strategy for mitigating atmospheric CO2 levels, offering environmental and economic opportunities. This thesis targets the Bunter Sandstone Formation within the Rødby structures in Denmark, focusing on seismic Profile 1.

3. 2. Sporadic-E layers in the polar cap ionosphere : A review on Es occurrence, dynamics and formation theory

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Anton Thorell; [2023]
   Nyckelord :Sporadic-E layers; plasma physics; space physics; arctic geophysics; radar technology; UNIS; Svalbard; EISCAT.; Sporadiska E-skikt; plasmafysik; rymdfysik; arktisk geofysik; radarteknik; UNIS; Svalbard; EISCAT.;

   Sammanfattning : Sporadic-E layers (Es) are layers of metallic ions that appear in the lower E-region of the ionosphere and can last from under one hour to several hours. Es are found at all latitudes, but polar cap Es, and specifically over Svalbard at a latitude of around 78◦ , are the focus of this study. LÄS MER

4. 3. Monitoring of heat exchanges in thesnowpack of Foxfonna glacier, Spitzbergen,Svalbard.

   Kandidat-uppsats, Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

   Författare :Thibault Desjonquères; [2022]
   Nyckelord :Glaciers; Glaciology; Svalbard; Geophysics; Superimposed Ice; Foxfonna; Geology.; Physics and Astronomy;

   Sammanfattning : The processes of meltwater storage in firn and the impact of refreezing on firn-coveredglaciers have been investigated on the Greenland ice-sheet. On Svalbard, climate changepromotes the disappearance of firn on glaciers. LÄS MER

5. 4. Comparison of Magnetic-Susceptibility Models From UAV-borne and Ground Measurements in Enåsen Area, Sweden

   Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Clara Sjödin; [2022]
   Nyckelord :magnetic susceptibility; Enåsen area; UAV survey; magnetic anomalies; Potent; magnetisk susceptibilitet; Enåsen; drönare; magnetiska anomalier; Potent;

   Sammanfattning : Mapping anomalies in the Earth’s magnetic field is one method used in applied geophysics, for exploring buried structures and objects. Magnetic surveys can be ground-based or made airborne, onboard airplanes, helicopters, or unmanned aerial vehicles (UAV), also known as drones. LÄS MER

7. 5. Reprocessing of Marine Reflection Seismic Data from Skåne, Sweden

   Magister-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Charlotta Carlsson; [2022]
   Nyckelord :Reflection seismics; marine geophysics; Claritas; Claritas; reflektionsseismik; geofysik;

   Sammanfattning : During 1979, an oil prospecting project was initiated in the south of Sweden, outside the coast of the municipality of Skåne. No drilling program was initiated, and the project was put on ice. However, with the oil prices of today and the interest in carbon dioxide storage, the area could once again be interesting. LÄS MER
